Welch Boltimate is a core-shell material with a 1.7 μm diameter non-porous solid core, and a 0.5 μm porous outer shell. Boltimate can deliver speed and efficiency rivaling UHPLC, using conventional HPLC systems at much lower back pressure.
Highlights
- Achieves efficiency similar to sub-2 μm materials (~200000 p/m)
- High speed and high resolution
- Compatible with both HPLC and UHPLC systems
- Operates at low pressure, but is stable up to 600bar (8700 psi)
